Evaluation of effectiveness of perfusion index model in acute artery occlusion

Peripheric perfussion index calculated by means of pulse oximetry by expressing the pulsatile signal (during arterial in flow) as a percentage of the nonpulsatile signal, both of which are derived from the amount of infrared light absorbed by a probe of the fingertip. Provide information about the patient's cardiac output , peripheric perfussion and hemodynamics. At the same time it is an inexpensive and non-invasive bedside method. It is possible to use in many clinical situations with these features and there are new research. Artery occlusion should occur with atherosclerotic vascular disease and trauma as well as external factors such as offending and compartment syndrome caused by a non-sparse clinical application in emergency medicine. Over 18 years old healthy volunteers admıtted to Adnan Menderes University Medical Faculty the emergency department between January 1 toMarch 1, 2015 were ıncluded to our study. The case report form was prepared for patients should be recorded in. With first arrival TA and PI values, TA and PI values in the different case of occlusion were recorded on this form as described below. In our study, including 68 (54.40%) women and 57 (45.60%) men of the total of 125 healthy volunteers. To prove the oretically that volunteers in the study have no peripheral arterial disease ABI (Ankle-Brakial Index) were measured and the ABI>1 patients were included in the study. In our study, baseline blood pressure values were determined using the appropriate blood pressure cuffs on the extremities to create a model of acute arterial occlusion. The cuff was inflated to the 1/3 of basal blood pressure values and PI measurements were performed. Then the half of the baseline value inflated and the PI measurements were performed. Finally, to be on the basal blood pressure values (full occlusion) was swelled and taken measurements. In patients improved and rested for 10 min between each measurement. In all subjects in the study average years was 32, mean of systolic arterial pressure 110 mmHg, mean of diastolic arterial pressure 76 mmHg, mean of pulse 95, mean of respiratory rate 23 has been identified. The mean age of the women volunteers participated in the study was 30, average age of the male volunteers 36 were also determined. So that the avarage age of a big difference between men and women volunteers was shown to be a great also. Between the all volunteers received study PI develops avarage was 4,2, PI 10. minute avrage was 3,2, PI 20. minute avarage was 2,5, PI 30. minute avarage was determined as 0,7. In our study, the arrival of PI compared with the other three dimensions, PI10. minute with the other three dimensions, PI 20. minute compared with the other three dimensions, PI 30. minute compared with the other three dimensions and found statistically significant differences from each other. When we evaluated the results of the study we found that the increase in cuff pressure perfusion index mean value were decrease. When the differences analyzed these changes were statistically meaningful. The model we created the PI has been able to detect reduced perfusion in all three pressure levels. Perfusion index measurement bedside admitted to the emergency clinic as an easily applicable method and identification of patients with suspected arterial occlusion and / or appears to be a method that can be used for follow-up.
